EELING-Em-SLACK-CONTROLiING MECHANISM FOR LOOKS.

To all whom it may GOMETIZ.

Be it known that l, Anouzo E. ltnoaons, a citizen of the United States,residing at Hopedale, county of Worcester, State of Massachusetts, haveinvented an improve ment in l illing- End Slack Controlling Mechanismfor Looms, of which the following description, in connection with theaccompanying drawing, is a specification, like characters on the drawingrepresenting like parts.

In looms provided with automatic filling replenishing mechanism theseveral filling carriers are mounted ready for use in a suitable hopperor feeder from which they are transferred singly to the lay as required.The filling ends from the several filling carriers of the supply hopperor teeder have to be securely held as the filling carrier is transferredto the lay and picked across the loom. it has been found that the sharpblow of the picker on a shuttle having a fresh supply of fillingsubjects the filling end to such a shock that it frequently breaksbefore the filling loegins to unwind from. the end of the fillingcarrier. Various means have heen devised to overcome this objection loyproviding an additional length of filling end between the pointvvherethe filling end is held and the filling carrier in the hopper. But thisadditional amount or slack cannot he left loose to he caught in themechanism or entangled withthe other filling ends. it is found, that itthe slack of each filling end was arranged to he held substantially tautby a spring or yielding device that the strength or power of such devicewhich is necessary to hold the slack filling substantially taut issuficient to place such a strain on the filling when the filling carrieris transferred from the hopper as frequently to break the filling.

lhis invention provides a means for positively controlling the slack inthe filling ends so as to keep the ends substantially tent and separatedand at the same time positively insure the release of the slack when thefilling carrier is transferred so that no strain will he placed upon thefilling by the retention of the slack to cause the loreahng of thefilling.

The invention therefore, in its preferred form provides a separate catchor detent for each run ot slack filling end and means automaticallyactuated upon the transfer of a o li carrier to the lay to give apcsihvo Specification of hetters Patent. Application filedhugust t,1913. Serial Ho. mar a.

relative movement to the catch or detent and its filling to release theslack filling without strain being placed thereon.

lhe nature of the invention will appear snore fully from theaccompanying descriptron and drawings and will he particularly pointedout in the claims.

lhe drawings show so much of an automatic filling replenishing'loom ofthe Northrop type as is necessary to illustrate this invention togetherWith a preferred form of the invention applied thereto.

in the drawings :-Figure l is a front elevation partially in crosssection of a filling feeder or hopper of this type of loom with afilling end holder and a portion at the lay with the present inventionembodied therein. Fig. 2 is an end elevation partially in cross sectionand partially broken away of the part shown in Fig. 1. Fig. 3 is adetail in end elevation showing certain parts in a difierent positionfrom that shown in Fig. 2.

A reference to the patent to Mason No. 628,226, granted July l, 1899 andthe patents therein referred to will make clear the general nature ofthe loom construction which is partially. herein shown and in viewthereof it wil he unnecessary to describe and explain the mechanismother than that directly concerned With this invention.

The filling f eder or hopper comprising the-disks or plates a, a, thehub or sleeve a connecting them to rotate on the stud the transferrer fto act against the head of a filling carrier 5 and provided with afinger 210 to act against the tip of the filling carrier, the lay ithaving the usual hunter to actuate the transierrer, the disk-likefilling end support I), the stud F9 to which the ends of filling aresecured,-the spring-controlled dog m mounted on the depending end P ofthe transferrer, the actuating rock-shaft (Z, the controllingconnections hetween this rock-shaft and the dog, these and other partsof the loom mechanism illustrated may he and aresuhstantially as shownand described in the said Patent No. 628,226.

The disk-like filling end support I) is provided peripherally withnotches as may be seen in Fig. 2., there losing one of these notches foreach filling carrier 5. Filling ends are led from the filling carriersheld in the disks 0, a over the disk I) each resting in its proper notchand are then wound about the stud 5 To provide the required slack. thefilling ends are not led directly from the disk a ofwthe hopper to thedisk b but are deflected as shown at 6'2. The slack thus formed is takenup as the carrier is transferred from the hopper wi great suddenness andeven a light pressure placed upon the slack to hold it suhstan tiallytaut will be sufiicient upon the sudden jerk of the transfer of the filing carrier to cause the breakage of the slack thread with a consequentimperfection in the fabric.

This invention provides for the positive release of the slack portion ofthe filling end so that no pressure is placed upon the slack to hold itdeflected at the time the transfer is made andthe slack is taken up. Apreferred and practical form of mechanism for securing the results ofthis invention is illustr'ated in the drawings and will now bedescribed.

The hub of the filling end support I) is provided with a sleeve 1 onwhich are limounted' concentrically two ring members 2fand3. The ringmember 2 at its periphery Tie-provided with generally radial slots 4 onefor each filling end and consequently these slots are spacedequi-distantly. The ring member 3 carries a corresponding plurality ofdetents 5 pivotally mounted at 6 on-the face of the ring 3 near theperiphery jand with their ends 7 normally. pro ected across thecorresponding slots 4 so that if a filling end he in a slot 4 with thedetent end 7 in normal position the filling end will be retained therebyin the slot and held 85 Ideflected as shown in Fig. 1.

The detents 5 are shown as small levers having the tails 8. Each detentis normally held in position across the slot and for this purpose a stop9 projecting from the ring memher 3 adjacent each detent positions itacross its slot and a helical spring 10 located in the rim member 3 andsurrounding the pivot 6 an attached at one end to the detent and at theother end to the ring member which serves normally to hold the detent upagainst its slot pin 9. The end 7' of the detent may also he notched orformed with a shoulder which is shown, to

. form a filling end receiving surface. The

side of each dctent toward its sl 5 is inclined as shown at 11. Tothread up the hopper each filling end is therefore brought down from theperiphery of the dish a and slid over this inclined edge of thecorresponding detent 5-forcing the detent hack and causing the fillingto slide up in the corresponding slot 4 until it passes the shoulderedend of the detent when the detent snaps back against its stop 9 and thusholds the filli in the slot. The filling end is then carrie 11 over thecorresponding notch in the dis b and thenwrapped about the stud b 4Theainvention provides positively actuated means for tripping eachdetent 5 as the corresponding. carrier is transferred to the lay thuspositively to release the filling end from the slot and allow the slackto be taken up without any pressure or retarding action upon the fillingend. A

preferred form of such means is illustrated in detail in Figs. 2 and 3.For this purpose the usual actuating rock-shaft d is extended beneaththe hopper and an upwardly projecting arm 12 is fastened thereto by thesetscrew- 13. This arm at its u per end carries a short stub-shaft 14 anon this stub-shaft is mounted a second rearwardly projecting arm 15. Thearms 12 and 15 are secured to the stub-shaft 14 by set-screws 16 and 17by means of which the arms may be set at a required angular adjustmentto each other and when set the two arms together form a bracket support.At the end of this bracket support toward the lay a lever 18 isfulcrumed at 19 and projects above andhelow the support. -A'striker-arm20 is pivoted at 21 to the upper end of the lever 18 and has one endprojecting rearwardly beneath the detent ends and the other end slottedat 22 and riding over a pin 23 projecting from the bracket support. Ahunter 24 is pivoted at 25 to the lower end of the lever 18, has itsrearward end projecting toward the lay and the opposite end slotted at26 and riding over a pin 2T also projecting from the bracket support. Ahelical spring abuts against a projection 29 on the lever 18 and thusacts normally to maintain the striker arm retracted and the hunterprojected toward the lay. The lay is provided with a projection 30 tocooperate with the hunter 24. The hod of the striker arm is located atone side 0 the path traveled by the tails 8 of the detents durin therotation of the hopper but has a projecting end 31 which when thestriker arm is raised projects into the path of the tails 8. The partsare so proportioned and arranged that when the actuating rockshaft d isin its normal position as shown in Fig. 2 the end of the striker armwill be below the path of the tails 8-0f the detents and the end of thehunter will he below the path of the projection 30 as the lay heats up.Upon the call for filling replenishment the shaft'd rocks carrying withit the bracket support and raising the position of the striker arm andhunter. The end 31 of the striker arm then passes in the rear of thetail 8 of that detent which holds the filling end running from thefilling carrier to he transferred and the hunter 24 comes in the path ofthe projection 30 on the lay. If now, the transfer of the fillingcarrier takes place and the bracket support is thus kept in its elevatedposition, the projection 30 on the lay as it heats up into transferposition strikes the hunter 2%, and through the lever 18 projects thestriker arm 20 caus- 1.
